碰撞截面 meaning in English
collision cro section
collision cross section
collision cross-section
Examples
- Calculation of scattering cross section of the electron and the second period element atom
低能电子与第二周期元素原子碰撞截面的理论计算 - By analyzing the differentiae of the total cross sections ( tcs ) , the differential cross sections ( dcs ) , the partial wave cross sections ( pcs ) , the change patterns of the cross sections and the influence on the cross sections because of the var iations in the mass of systems and the relative kinetic energy of incoming atoms for symmetric isotopically substituted systems he , ne , ar , kr , xe - h2 , d2 , t2 have been obtained . in this paper , we use the tang - toennies potential model for the inertia gas atoms - h2 systems , the murrell - sorbie potential surface with five parameters for the molecules h2 , d2 , t2 . for the inertia gas atoms - d2 , t2 systems , we use the same potential surface with the inertia gas atoms - h2 systems
通过分析he 、 ne 、 ar 、 kr 、 xe ? h _ 2 、 d _ 2 、 t _ 2各碰撞体系在总截面、微分截面和分波截面等方面的差异，总结出在h _ 2分子的对称同位素替代情形下惰性气体原子与h _ 2分子体系碰撞截面的变化规律；通过比较he 、 ne 、 ar 、 kr 、 xe ? h _ 2 、 d _ 2 、 t _ 2各体系在碰撞总截面、微分截面、分波截面等方面的不同，详细讨论了同位素替代碰撞体系中体系约化质量及入射原子的相对碰撞能量的变化对碰撞截面的影响，得出了这种影响的规律性。 - And based on these findings , we further study the dependence of nuclear stopping on system size , initial n / z , sp and the medium correction of two - body cross sections . it ' s found that the effect of initial n / z ratio and isospin sp on stopping is weak , and the excitation function of stopping depends on the form of medium correction of two - body cross sections and the equation of state of nuclear matter strongly
在此基础上我们研究了核阻止本领对系统大小、初始核n / z 、平均场中对称势以及两体散射截面介质修正等的依赖情况，研究结果表明它受初始核n / z比以及对称势的影响很弱，而受碰撞截面介质修正的同位旋依赖效应及核态方程影响明显。 - The calculation results show that the correlation between the multiplicity of intermediate mass fragments n ( subscript imf ) and total number of charged particles n ( subscript c ) is a sensitive observable for probing the isospin - dependent in - medium nucleon - nucleon cross section , but the isospin effects of symmetric potential on n ( subscript imf ) is not obvious in the chosen energy region
计算结果表明在所选能区，中等质量碎片的多重性与带电粒子总数之间的关联是提取介质中核子核子碰撞截面的灵敏观测量，而此时对称势的同位旋效应却不明显。
